A couple of months ago, a pit bull named Sage was found loose in a Dallas neighborhood. Sage had been found with serious medical problems, and needed immediate surgery — which she got thanks to her rescuer and foster Karly Edington, who marvels that even at her worst, Sage was "wagging her tail throughout."

Edington took Sage home as a foster to her apartment, which she shares with another pit, Rosemary, who'd also been in acute need of medical help when she was rescued.

Edington felt a real kinship to the sweet and loving Sage. Sage and Rosemary instantly became "sisters," Edington tells The Dodo.

That call to action got retweeted by sports reporter Emily Jones. [https://twitter.com/emilyjonesmccoy?lang=en]. The exchange was spotted by Dallas Rangers pitcher Yu Darvish — a dog lover who already had five pups at home, including another rescue pittie. (Unrelated, but fun: Darvish was once called The Elvis of Japan by the magazine GQ.

He reached out to Edington on Thursday evening last week — and not being a sports fan, she wasn't initially sure who he was; Balis had to set her straight. On Friday morning, Darvish and his wife came to Edington's apartment to meet Sage.

At first they offered to take her home temporarily — with the aim of helping her get adopted by someone else.

“I thought, ‘What would happen to the dog if no one picked her up?'” Darvish, who speaks Japanese, said through an interpreter, according to Fox.

But that intention didn't last long. By the time the couple left with Sage, they were committed to keeping her for good.

"Proof that being a foster pays off. All the hard work, love, and endless amount of emotion I poured into Sage, and here is my thank you," Edington wrote on Instagram. "I am beyond grateful for this man, who simply saw a desperate tweet for help, and within the hour contacted me."

Shannon Glenn, executive director of the nonprofit My Pit Bull Is Family, tells The Dodo she hopes that Sage's high-profile adoption will help other pups find homes of their own.

"When an athlete or someone in the spotlight adopts a pit bull type dog not only does it raise awareness about adoption but it also helps break the stereotypes that many of these dogs face," she said. "I'm excited that Yu fell in love with Sage."
